‘The bus turned into the main street when there was a giant bang, an explosion. I sat in the last row next to Marc Bartra, who was hit by the shattered glass of the rear window,’ Dortmund goalkeeper Roman Burki told Blick.

The explosives used were hidden in nearby hedges, while a suspect ‘from the Islamist spectrum’ has been detained, according to German officials.

‘The consequences could have been far worse,’ said Frauke Kohler, a spokesperson for the federal state prosecutor in Karlsruhe.

‘Two suspects from the Islamist spectrum have become the focus of our investigation.

‘Both of their apartments were searched, and one of the two has been detained.’
